I walk past Uncle Tetsu's every single day on my way to/from work and decided to finally try it out a few mornings ago when there was barely a line. I purchased one cheesecake for $10 and shared it with some co-workers. Honestly, we weren't too sure what the hype is about. Yes, it's fluffy, spongy and lighter than most cheesecakes, but it's nothing I would line up for on a regular basis. We ate it at lunch after it being in the fridge for a few hours and it tasted ok. I always see long lines so I assumed it would be some really amazing cakes so I was a bit disappointed.
It's sort of an assembly line style place in that you just pick up your cake and leave. It might be more appealing for some if you had somewhere to sit and enjoy it. Either way, it's somewhere I might be inclined to pick up a cheesecake from if there were no line and it wasn't out of my way, but not somewhere I think warrants the crazy lines. The packaging is cute though!
